VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jan 29, 2015) - GREAT PANTHER SILVER LIMITED (GPR.TO)(NYSE MKT:GPL) ("Great Panther", the "Company") announces an updated Mineral Resource Estimate at the Company's wholly-owned Guanajuato Mine Complex ("GMC") in Guanajuato, Mexico, including updates on the Guanajuato ("GTO") and San Ignacio ("SI") Mines and the El Horcon Project. The updated Mineral Resource Estimate does not include the most recent drill results at San Ignacio and the discovery of high grade silver-gold mineralization to the south of the existing resource block (see news releases Oct. 30, 2014 and Jan. 27, 2015). This new data will be the subject of a further resource update later this quarter.

Highlights of the updated Mineral Resource Estimate are as follows:

• Updated Measured and Indicated ("M&I") mineral resources at the producing operations of the GMC (Guanajuato and San Ignacio Mines) comprise 349,700 tonnes at a grade of 260g/t silver ("Ag") and 3.32g/t gold ("Au"), containing 5,558,000 silver equivalent ounces ("Ag eq oz"), using various silver equivalent ("Ag eq") cut-offs in the different mineralized zones.
• Inferred mineral resources at the producing operations of the GMC are estimated to comprise 451,900 tonnes at a grade of 147g/t Ag and 3.34g/t Au, containing 5,556,500 Ag eq oz. Different cut-off grades were used for the mineralized zones as indicated in the tables below. Including the non-producing El Horcon Project, Inferred resources comprise 601,100 tonnes at 130g/t Ag and 3.38g/t Au, containing 7,637,700 Ag eq oz.

"This latest Mineral Resource Estimate for the GMC represents a 37% increase in Measured and Indicated Resources despite the impact of much higher cut-off values due to the decline in metal prices in 2014. In addition, we expect a resource update before the end of the quarter from the recent drilling completed at San Ignacio," stated Robert Archer, President & CEO. "We have also increased our 2015 drilling budgets for both San Ignacio and Guanajuato. This will allow us to further delineate the recently discovered high grade mineralization at San Ignacio and increase our confidence in the deep resources at the Guanajuato Mine."

The 2014 Guanajuato Mine Mineral Resource Estimate contains Measured and Indicated mineral resources of 3,757,800 Ag eq oz including 3,190,300 Ag eq oz in the Measured category and 567,500 Ag eq oz in the Indicated category. Inferred mineral resources are estimated at 1,782,200 Ag eq oz. These are all contained within the Cata Clavo (seven zones), Los Pozos (two zones), Santa Margarita, San Cayetano, Promontorio, Valenciana (five zones) and Guanajuatito (five zones) areas. The Guanajuatito ("GTTO") area has been expanded with the addition of the Intermediate zone located in the foot wall to the GTTO hanging wall zone. Resources in the Santa Margarita and Cata areas have also been increased.

Mining of the Cata, Los Pozos, Santa Margarita and Guanajuatito areas currently accounts for most of the Guanajuato metal production. This updated mineral resource will help in guiding development and improving grades at the mines. Underground drilling has resumed in 2015 with three drill rigs to delineate new resources on the upper extensions of Los Pozos SE and Santa Margarita, and the up-dip and northwest extensions of the Cata Clavo zones.

Summary Table of 2014 Mineral Resource Estimate for the Guanajuato Mine Complex¹

The 2014 San Ignacio Mine Mineral Resource Estimate contains 1,800,200 Ag eq oz in the Indicated category, in the Intermediate and Melladito veins. Inferred mineral resources are estimated at 3,774,300 Ag eq oz and are contained in the Intermediate, Melladito, Nombre de Dios and Nombre de Dios II veins. Recent surface drilling at San Ignacio has discovered that the Intermediate and Melladito veins merge, just south of the aforementioned resource block, into a thicker, higher grade lens of silver-gold mineralization. The data from this program are presently being compiled, interpreted and modelled, and a new San Ignacio Mineral Resource Estimate will be announced in the first quarter 2015.

Mining at San Ignacio in 2014 was focused on the Intermediate vein and, to a lesser degree, the Melladito vein. As the two merge to the south, the single vein will retain the Melladito name. Underground drilling in 2015 will be focused on improving the classification of the resource on this new zone, while surface drilling will test the depth and strike continuity of all veins.

The 2014 Mineral Resource Estimate for the El Horcon Project (see table below) includes only the Inferred classification of 149,200 tonnes containing 374,200 oz silver, 16,840 oz gold, 9,275,000 lbs lead, and 13,024,500 lbs zinc. There has been no additional drilling since 2013 and the resource update reflects only updated metal pricing, which resulted in a 7% decrease compared to the previously reported mineral resource. The El Horcon Project is not in production and the Company has no specific plans to advance the project in 2015 except by completing various environmental permitting that is already underway.

Overall, from the last Mineral Resource Estimate (effective date July 31, 2013), the Measured and Indicated classification increased by 37% (+1,487,900 Ag eq oz), while the Inferred mineral resource decreased by 22% (-2,206,250 Ag eq oz). Part of the difference is due to the conversion of Inferred Resources to M&I at GTO and SI. Management is committed to maintaining or increasing mineral resources at the Guanajuato Mine Complex, and has increased the drilling budget for 2015.

The estimates were classified according to the CIM Definition Standards on Mineral Resources and Mineral Reserves and, as such, are consistent with the requirements of NI 43-101. The mineral resource estimate was completed by Robert Brown, P. Eng. and Company, Q.P.

The Company's QA/QC program includes the regular insertion of blanks, duplicates, and standards into the sample shipments; diligent monitoring of assay results; and necessary remedial actions. Sample assaying was completed at the independent SGS-GTO lab in Guanajuato, GTO, Mexico. Silver assaying was completed with AAS12B technique, with over-limits (300g/t) completed by FAG323. Gold assaying was completed with FAA313 technique, with over-limits (10g/t) completed by FAG323. Where necessary lead, zinc, copper, arsenic and antimony assays were completed using atomic absorption spectroscopy.
